Title: Improvements in and relating to the regulation of electric generators
IPC: H02P9/00
Filed: 1930-07-17
Abstract: 359,030. Speed governors. SACCAGGIO, P. C., El Chalet, Remedios de Escalada, Ferrocarril del Sud, Buenos Aires. July 17, 1930, No. 21598. [Class 57.] The prime mover on a mixed power installation, such as a petrol electric locomotive, is prevented from racing by regulating means reducing the fuel or motive fluid supply in anticipation of the removal of load. This means is operated through a lost motion device from the generator controller and preferably acts through the governor gear. The generator controller handle 16 carries a friction pad which moves an insulating disc through a distance determined by two stops 14, 21, one of which, 14, completes the circuit of a solenoid 9 when the generator is to be loaded. This electromagnet places the governor link mechanism in the position shown in full lines, corresponding to normal position of the fuel valve controlled by the spindle 4. When the controller handle is moved to reduce the generator load the solenoid is immediately deenergized and a spring 9<1> moves the link mechanism to the position shown by dotted lines, corresponding to the idling condition of the fuel valve. Adjustment of the movement is effected by stops 22, 23 or by adjustment of the connection between the solenoid core and the link 12. The solenoid may be operated in steps by a series of contacts such as 14, 15 or it may be replaced by equivalent mechanical, hydraulic, pneumatic or like means.

Patent GB-727470-A (GB)
Title: Process of forming adherent polyethylene coatings on metal surfaces
IPC: B05D1/38
Filed: 1951-09-17
Abstract: An adherent-protective polyethylene coating is formed on a metal surface by bringing a mass of solid polyethylene particles in excess of that required to form the desired thickness of coating into contact with the metal surface which has been heated to a temperature of 350-475 DEG  F., and, while maintaining the heated surface covered by the polyethylene particles, causing a relative movement between the surface and the particles whereby the surface is subjected to a wiping action by the particles and is thereby brought into contact with additional particles which become fused thereon to build up the coating to any desired thickness, thereafter removing the excess of polythene particles and subjecting the coated metal surface to a baking treatment.  In one method of carrying out the invention, an open drum <PICT:0727470/III/1> which has previously been blasted with shot, sand or metal grits and preheated to the required temperature, rotates on driven rollers 10 in a slightly inclined position.  A feed hopper 14 discharges the polyethylene powder through a spout 16 into the raised end of the drum, overflow troughs 18 and 20 receiving the excess of powder.  The troughs overlap the lips 22 of the drum so that they also become coated.  Excess powder from the troughs 18 is conveyed to the sump 24 and thence back to the hopper.  This method can be applied to a drum closed at one end which is preheated, partly filled with polyethylene powder, inclined and rotated, the excess powder discharging from the lower end.  In another method, a five-gallon sheet metal pail heated to 450 DEG  F. is filled with the powder, stood for a brief interval and the powder is then manually pressed outwards from the interior on to the hot walls until the required coating thickness is obtained whereupon the excess powder is removed.  After the coating operation, the article may be baked in an oven at 400 DEG  F., preferably while being rotated, for from 15 to 40 minutes.  After baking the article is preferably cooled rapidly by directing an air blast or water spray on it.  The process is also applicable to the coating of sheets, strips and plates of iron, steel, copper, aluminium, tin, zinc, and brass.
Patent GB-865306-A (GB)
Title: Metal recovery process
Inventor: REED CORTES FREDERICK
IPC: C22B41/00
Filed: 1959-06-25
Abstract: Metal sulphides which are insoluble in dilute acids, especially germanium sulphides, are recovered from alkaline coal combustion residues in a process comprising washing the residues with water, treating the resulting solution with a water-soluble sulphide, and acidifying, preferably to below pH 5, to precipitate the metal sulphides.  The initial wash water may contain some or all of the water soluble sulphide, and the final acidified solution may be heated to below boiling, and preferably above 180 DEG F., to hasten the sulphide precipitation.  The water-soluble sulphide is preferably an alkali or alkaline earth metal polysulphide.  The preferred acid for adjusting the pH is hydrochloric acid, but sulphuric, phosphoric, nitric, and glacial acetic acids may also be employed.  In the case of germanium, the amount of sulphide employed is preferably in an amount sufficient to add sulphur in an amount from 0.02% to 0.2% by weight of the original coal residue.  If the coal residue is normally non-alkaline, an artificial alkaline residue suitable for processing may be obtained by adding alkali, for example soda ash, lime, potash, or caustic soda, to the coal prior to burning.  Other metals values which may be recovered include antimony, arsenic, copper, lead, iron, aluminium, gallium, titanium, uranium, gold, tin, platinum, and cadmium.  The sulphide precipitated may be freed from free sulphur by leaching, for example with carbon disulphide, or by distillation or controlled oxidation.  The sulphide precipitate may be roasted to give the oxide.

An X-ray system has at least two high-voltage generators and three X-ray tubes wherein any tube can be connected to any generator by a selective switching arrangement which connects any tube to a free generator and which prevents another tube from being connected to the same generator. The circuitry is arranged so that if all generators are in use, a tube will be connected as soon as a generator is free. Each tube may be associated with a remote controller connectible through a selecting arrangement to a regulating device for the generators. The regulating devices may also be connected to the generators through a selecting device, so that the regulating device may be preset and switched on to the generator with a tube. Each tube may be associated with high-voltage interlocked switches to prevent two generators being connected to one tube. Signalling devices may be provided on each controller to indicate the connection of an X-ray tube to a generator. The switching arrangements may be performed by telephone-type apparatus.
